3.0L Valve Clearance Adjustment

NOTE: Hydraulic valve lifters are used; no valve adjustment is required. If incorrect valve clearance is suspected, lifter must be collapsed before clearance can be checked.
  1. Position No. 1 piston at TDC of compression stroke. Slowly apply pressure until valve lifter is completely collapsed on No. 1 intake.
  2. Holding lifter in collapsed position, measure clearance between rocker arm and tip of valve stem. If clearance is not within specification, repair or replace components as necessary. See 3.0L COLLAPSED VALVE LIFTER SPECIFICATIONS table.
  3. Repeat procedure for exhaust valves No. 1, 2 and 4, and intake valves No. 3 and 6. Rotate crankshaft 360 degrees (one revolution). Repeat procedure for exhaust valves No. 3, 5 and 6, and intake valves No. 2, 4 and 5.
